FLYcATcHER. Y

useful improvements in fly catchers and has for its Vprimary object to provide a Hy catcher in the form of a glass or other transparent cup having a funnel-shaped cover constituting an entrance to the cup for the flies with a normally open outlet adjacent the upper end of the cup body.

A further object of the invention resides in the provision of a fly catcher in the form of a glass receptacle or cup wherein the removable funnel-shaped cover constituting" the entrance to the cup for the flies is provided with a plurality of depending concentric ribs, the continuity of which is varied by sections of increased area and reversely curved parts to create many different reflecting surfaces to assist in the retention of the trapped iies within the receptacle.

With the above general objects inview and others that will appear as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed. l

In the drawing, wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a vertical sectional view 0f a fly catcher constructed in accordance with the present invention showing the removable screw funnel-shaped cover with the depending annular ribs carried thereby, and

Fig. 2 is a horizontal sectional view taken on line II-I'I of Fig. 1 showing the various shapes and curvatures of the ribs and receptacle wall.

Referring more in detail to the accompanying drawing there is illustrated a fly catcher embodying a cup-shaped receptacle including a at bottom 3 and a perpendicular side wall 4 carrying a lifting handle 5 by which the receptacle is transported. The receptacle is open at its upper end and is provided with internal threads 6 for the threaded reception of a cover to be presently Specification of Letters Patent. Appncatipn mea August 6, 1920.

The type of cover:k employed herein embodies funnel-shaped wall Shaving a lower central reducedv open end 9 in proXimwall 3, the upper end of ity of the bottom carica" Patented Mar. 15,1921.

A constantly Open'OutletnOZZle i .through said nozzle while the coverremains i the funnel-shaped Acover' 8 having a lateral Y annular flange 10 positioned-n above the upper edge of the yside wall 4 and resting` on the gasket l1, the cover 8 adjacent the iangeY being' provided with a depending portion V12 of increased cross sectionallarea` and eX- ternally threaded as at 13 for threading engagement with the threads 6 in the-upper end of the side walls 4 of the cup. A lplurality ofconcentric circular walls depend from the funnel-shaped cover 8 and are designated by the` reference numerals 14,"v` 15 being of like cross sectional area over the entire surface thereof. For purposes of confusing paths of travel of the trapped insect, the and the inner faces of the side walls 4 are of various cross sectional areas andreversely curved, the wall 15 being provided with spaced sections 15 of increased cross sectional 'area while thel wall 16 is reversely curved as at 16 at points adjacent the enlargements 15 while the walls 4 are of ineased cross sectional area as indicated at parts 16, providing reduced passageways between the respective walls depending from the cover section and the side walls of the receptacle.

The quantity of fluid indicated by the reference character a isplaced within the receptacle with the upper level thereof ad- Vjacent the lower edges of the depending walls 175 and 16,V

at points adjacent the reversely curved i walls 14 15 and 16' at the restricted pas sageways between the respective walls and upon dropping downwardly, the trapped insects will fall vinto the body of fluid and 5 beV retained within the receptacle. `llhen it is desired to empty the contents of the `receptacleitis unnecessary toremove the cover as the outlet spout is provided `for this purpose, the fluid and insects Vtrapped within the receptacle escaping through the outlet nozzle. For purposes of cleaning-the receptacleythe cover is unscrewed therefrom `and the faces of the several walls depending fromlthe coverlnay` be cleaned and the receptacle placedL in Fa `perfectly sanitary condition. u

While there is herein shown and described Athe ,preferred -embodiment of the present invention, `-it is nevertheless tobe under-- stood "that minor changes may ybe made "1 therein withoutvdeparting from the spirit and scope ofl the invention vas claimed.

What I claim as new"i`s:`` A flylcatcher ofthe `type described cornprising a receptacle havin g 1 internal screw threads at the upper` endthereof, a1 funnelshaped cover having an externally threaded depending shoulder port-ion"` screwed into the upperendof the receptacle, and a plu- 80 rality of concentric walls `depen-ding from thefunneLshapedcovenr r K n 2. A'fly catcherof the typedescribed comprising a receptaclehaving internal screw threads `atqthe upper end thereof,-a funnelnsvivo shaped cover having an externally threaded depending. shoulder portion screwed into the "upper'c'nd of therceptaele, and a plurality of concentric walls depending from `"thefunnehshaped cover, some of said walls having spaced sections of increased cross sectionalarea and others of said walls having spaced reversely curved sections.

3. A fly catcher of the type described comprising a receptacle having internal screw threads at the upper endv thereof, acfun'nel- Vshaped cover havingr an externally threaded depending `shoulder ,Y portion `screwed. into Athe upper end of thereceptacle7V a plurality of concentric walls depending from the funnel-'shaped coveryand a'n outlet spout formed Y in the receptacle adjacent the upper end thereof.

4. A flycatcher of the typedeseribedcomprising a receptacle,'aj-funnelfshaped cover removably supported Athereon and having the lower end thereof Vconstitutinga reduced opening to the receptacle, and a plurality of concentric fwalls depending from said funr nel-shaped cover with the lower ends thereof lying in the -sarne plane 'lasV the ventrance opening to thereeeptacle.
